英文摘要	As a kind of refining agent, Al-Ti-C-Ce intermediate alloy is widely used in the field of nonferrous alloy smelting. The effect of Al-Ti-C-Ce contents on microstructure and properties of Al-Cu-Mn alloy was studied by OM, SEM, EDS and other test methods. The results show that the as-cast microstructure of Al-Cu-Mn alloy is obviously refined after adding 0.1% Al-Ti-C-Ce, and the θ phase is characterized with the shape of point or strip. With the increase of the addition amounts, parts of the grains coarsened. When the addition amount reached to 0.3%, the refinement effect of the alloy microstructure was further reduced, and the number of intergranular precipitates TiC and Al3Ti increased. Ductile fracture is the main failure mode of the alloy. After T6 heat treatment, the grain size changed little, and the number of θ phase, TiC and Al3Ti decreased, changed from the mesh to the point or needle or strip structure, and the proportion of alloy ductile fracture increased. The addition of Al-Ti-C-Ce has positive effect on improving the microstructure and properties of Al-Cu-Mn alloy. © 2018 Trans Tech Publications, Switzerland.
